TO ALL -WOM IT MAY CONCERN:

Beit known that I, 'HENRY SEHEN, of the city andjcounty oi St. Louis, the State of l\'Iissouri,.have invented a new and improved Mode of. Ventilating Rooms; and. I ydo hereby declare that the following is a full and exact description thereof, referencebeing had to the accompanying drawing, and to the letters of reference Y marked thereon, like parts being designated by like letters in the several gures.

The nature ofmy invention consists in constructing awheel having inclined and radial fans, buckets, or wings, their surfaces being nearly parallel with each other, and having openin'gsbetwoen them; said wheel having a central hub, and turning or revolving on a supporting bracket, turnedor propelled by heated air ascending from the flame of a lamp, lighted gas, or similar-flame.

Tov enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation. In the drawings I Figure A1 represents a top or plan view of my Ventilating machine.

Figure 2, an elevation of same, showing how supported andV attached to a as pipe.

Figure 3 is a section of central hub. v

A represents the radial wings, 'fans ,or buckets, secured in any suitable way to a central ring, B ,so that they can be easily put 'in place orA removed, or the angie of inclination be varied. There are openings or airspaces between these radial buckets, which, however, overlapeach other. The ring, B, is connected by several radial strips, b, to a central-hub, G, which-has a central hole or opening, c, in its lower end, and in which .a snpporting bracket, D,=is`placed,=and-onwhich the wheel, A, revolves. This bracket again has its suitable'support; as shown, is held by a compound.clampE, which hugs a vertical gasfpipc F. These adaptations are varied by circumstances, fbeinga mere matter of mechanical fitting and convenience.

The operation is simply as follows: Taking, for example, a vertical gas-pipe, pendent or dropping from the ceiling, and having a'horizo-ntal arm, on.which there is a burner, the clamp Eis first secured to pipe F (hugging it) by means of two screws, p, andsay ,a foot, more or less, abovethe horizontal arm referred to, The lower end, f, of bracket D is held by this clamp,.E. The 'hub of wheel A is now placed on the other or top end, s, of the bracket ,f\which entersthe lowerhole, c, and passing, upward goes into a centrali-hole, d, of an upper plate, e; just above this plate, e, there `is aglass plate, f, which is held in place by another plate or disk, g, above it, which is secured to the top of -the hub, holding e and f inplace. This arrangement, say, brings the wheel A some two feet, more or less, above anddirectly over the flame of lighted gasat. the end of horizontal arm. A heated columnof air .ascends from the lame,1vwhich has moreor less motion and'foice.l This heated air impinges against the inclined under sides of the radial wings or 4buckets and passes on up between 'therin-.at same time generatinga revolution of the wheel, which acts as a iau, mixing or disturbing, more or less, the atmosphere of 'a room, producing a current, acting 'as a ventilator, and assisting in driving out impure air, if there be any egress for it. AnotherV advantage is the following: that the underside of the wheel will catch most of the products of combustion and retain them, thus preventing to a: great extent any soiling of the'ceiling above. The wheel can be removed' at any time very easily;` be cleaned; if of metal, brightened or polished; and it will serve as a reflector when revolving.4 -The under side of wings may have a covering of looking or other glass for such purpose. I prefer constructing my machine of metal. However, different materials may bc used, separately or in combination. The` object ofglass pla-tof', (it ybeingv the bearing ofy wheel A on bracket IL) is to avoid friction and lead to a more rapid revolution of the wheel, thus increasing its utility.

I am aware many wheels have been constructed to be driven by water, steam, and even wind, tholattcr commonly called windmills. I am also awarep'f .the Hutter wheels,usually placed inwindows forventilating purposes; but'thesel do not claim. It willbe seen that mine is diiferently constructed, applied, and operated than any others heretofore known. The buckets ofmy wheel are easily put in or taken outcleaned, and their angle changed, as well as their purposes multiplied or increased, as set `forth; so that the wheel, as constructed, supported, and applied, is novel aswell as useful.v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is'- A Ventilating wheel, constructed, operated, and applied i'n the manner as shown and described, and for the purpose set forth. v

HENRY SEI-IER.
